Be the one

A blonde character with a mechanical arm and red cape stands in a dimly lit space, then turns and runs forward. A silver-haired character with glasses looks intensely at the camera while holding a device. A white-haired character in a white coat swings a sword at an opponent. A character with dark hair and a white shirt fights a red-haired character in a classroom. A character in a purple outfit swings a large weapon, sending sparks flying at an opponent. A character in a white outfit with a pink headband fights a character in a green and black patterned outfit in a forest.
